'TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No.

294,528, dated March 4., 1884.

Application filed December 29, 1883. (No model.)

ments in Light Vehicles; andI do hereby de clare that the following is afull and exact description thereof, reference being had to theaccompanying drawings, making part of this specification.

My invention consists in improvements in trussing the poles, hounds,axles, and seatsupports of light vehicles for driving-sucl1 aspole-carts and s'ulkiessubstantially as hereinafter specified.

I11 the drawings, Figure 1 represents a top View of the pole andconnected parts of a light pole-cart to which my improvements are applied or with which the said parts are connected; Fig. 2, a side view ofthe same; Fig. 3, a top View of the similar parts of a sulky constructedwith my improvements; Fig. 4, a

side view thereof; Fig. 5, a rear view of the trussed axle; Figs. 6 and7, views showing some of the construction in detail; Figs. 8, 9, and 10,respectively, a front view, bottom trussing.

Like letters designate corresponding parts in all of the figures.

. vals by any suitable means.

' strips, a a, as shown, so as to be separated in the center First, asto the construction of the pole A. I truss it substantially in thefollowing manner: It is formed of threetrussepieces namely, two outerstrips, to a, and a central strip or brace, b. The three parts aresecured together at the two ends of the pole, and the two outer arecurved outwardin the middle,

as far as may be desired for strength and stiffnes's, say two or threeinches. The middle piece, I), is straight,- and consequently there isequal space on both sides between it and the side pieces. The parts areconnected at intervI have represented bolts 0 0 extending through thethree parts, with thimbles or washers d (1 around the bolts between theparts, as shown by the cross section in Fig. 6. The strips may be allmade of strong but comparatively light wood, and quite thin, notexceeding five-eighths of an inch for a light pole-cart or a sulky. Thetwo rear end, f, of the section of my seat-support" -and stiffness aregiven thereto to enable outer strips may be sawed from one piece andsplit the full length of the trussing, and for sulkies, as shown inFigs. 3 and 4, the curved pole not being split, but whole, as shown.

. Another feature of improvement in the constructionof the trussconsists in widening the middle strip, 1), in the middle beyond thewidth of the outer strips, a a, as shown in Figs. 2, 4, and 6. The widthmay be twice as great at the middle as the outer strips, and graduallynarrowedto the same width at the ends of the truss. This form givesgreat rigidity and strength to the pole in the vertical direction, whilethe bending outward of the outer strips gives sufficient rigidity andstrength horizontally. Thusa very strong as well as light pole is formecThis construction is applicable to the poles of all kinds of vehicles.It is obvious that this feature of widening a strip, 2), is-applicablealso to two strip trusses as well as three-strip trusses, either one orboth strips being thus widened in the middle.

The next feature of improvement consists in splitting and trussing thefore part of the houndsB B, Figs. 1 and 2, forward of the cross-brace g.The bulging out of the two sides h h of the trusscd part and the staysor braces between stiffen the hounds greatly with out increasing thematerial and weight. The rear curved parts of the hounds are preferablyretained whole without trussing.

Another feature of my invention consists in formingatrussed arched axleD, substantially as herein described, whereby sufficientstrength me todispense with a straight brace-rod extending from spindle to spindle ofthe axle. The arch is made high, and is trussed by combining two archedstrips, 6 j, of different degrees of curvature, as shown in Fig. 5, sothat the strips are united at the two ends where they are joined to thespindles 7c 70, and separated farther and farther toward the middle.They are braced together at intervals, preferably by means of doubleclips Z Z, as shown in Fig. 7. The strips 13 j are suitably made of fiatform on the adjacent sides, but rounded on the outer sides. For a sulky,the body may rest directly on a flattened or straight portion, m on thehighest part of the upper strip, 7?; or an elliptic spring may bemounted on this strip under the seat.

Another feature of myinventiou consists in my improvedseat-supporttrussing for these light vehicles, as shown in Figs. 8, 9, and 10. Let Drepresent the axle or upper trussstrip of the axle; E E, side shafts; FG H, crossbars between the shafts, and I the seat or seatframe.

First. I employ a T-shaped brace, 01, coir necting the seat I and frontcross-bar, F, in the middle, as best shown in Fi g. S. This not onlysupports the seat in the middle of the front part thereof, but braces itagainst side rackin It also forms, in connection with two inclined sidebraces, 0, between the seat and said cross-bar F a complete truss,producing great strength and firmnessin the sup port, though the partsmay be quite slender and light.

Secondly. This front brace, 21, in connection with a brace, 1),extending from the cross braces, or braces F G, to the axle l), or aclip, q, thereon, a brace, 1', extending fromtheaxle or the said clipthereon to the rear cross-bar, H, and a brace, 8, extending from thecrossbar H to the seat I, forms a complete trnssing of the parts fromfront to rear.

I claim as my invention- 1. A trussed vehicle-pole formed of two outthemiddle and narrow at the ends, for the purpose specified.

3. In combination with a vehicle-pole, hounds trussed in the partforward of the cross-brace, substantially as and for the purpose hereinspecified.

4. Au arched axle trnssed with two arches of different degrees ofcurvature, substantially as set forth.

5. The T-shaped brace 11, in combination with the cross-bar F and seatI, for the purpose specified.

G. The combination of the brace 01, braces 0 o, cross-bar F, and seat I,substantially as and for the purpose herein specified.

7. The combination of the braces n p r s, cross-bar F, axle D, cross-barH, and seat I, substantially as and for the purpose herein specified.

In testimony whereofI have signed my name in thepresenee of twowitnesses.
